A few players wrote some guides for MP in MTW; I am one of them.

My opinion on your idea is:

In the current state of the game, with all the bugs and problems, either the patch will change a lot of things and you'll have to rewrite the guide after the patch, or it does not, and RTW MP is dead in 3 months. So why bother?

A second point to consider; I think it takes a couple of hundred games to start to figure out how to play this game. Another couple to really figure out what beats what, and how to use each unit.

It's too early... and things keep going the way they go, soon there won't be a MP game to write a guide about
